1 Claim.

The invention'relates to a bunch and filling builder and more especially to a filling and bunch'builder mechanism for yarn winding machines and spinning'frames that areadapted to lay a preliminary winding or bunch on the bobbins or yarn receivers prior to the laying of the main service winding thereon.

The primary object of the invention is the provision of mechanism of this character, wherein 1 the same is wholly automatic in its operation and is adjustably carried by the frame of the machine so that the latter will run twenty-five to thirty minutes longer according to the number of yarn and effects the winding of the thread 1 tighter on the bobbin, eliminating'all high end pieces and places a great deal more yarn on the bottom of the bobbin and materiallyminimizes waste.

Another object of the invention is the provision of mechanism of this character, wherein the yarn production is greatly increased both in spinning and weaving and results in a better grade of cloth.

A further object of the invention is the provision of mechanism of this character, wherein the filling runs from two to two and one-half minutes longer in shuttle.

A still further object of the invention is the provisionof mechanism of this character, which 30 is simple in construction, thoroughly reliable and efficient in its operation, readily and easily applied to the frame of a spinning machine, wholly automatic in the working thereof and inexpensive to manufacture and install.

5 With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses. the

" '0 preferred embodiment of the invention, and

Similar reference characters indicate corre-' sponding parts throughout the several views in 5 the drawing.

Referring to the drawing in detail, the invention herein illustrated is applied to a ring spinning machine wherein the head end A is fastened to-bolster rails Ill the top of which supports a series of spindles provided with whirls H for 5 rotating 2. series of yarn bobbins l2 mounted on the spindles. A lifter rail l3 has a series of rings !4 provided with the usual travelers and is supported by a lifter rod I5, the lower end l6 of which rests upon a roll I! mounted on the cross '10 arm lever l8 pivoted at l9 upon a hanger 20 extending from the bottom of the bolster rail Ill. The lever I8 is counterbalanced by a weight l8 whereby the upward traverse of thering rail is effected. Extending upward from the lever l8 l5 is a segment arm 2| toMwhich is connected a chain, in this instance including two: separate lengths 22 and 23, respectively, and the'section 23 passes over the sheave pulley 24 and is then connected to the filling winding lever 25 working in conjunction with the builder lever 26 of usual construction pivoted on a stud 21 fixed to the head end A. While only a single lever l8 and lifter rod l5 are shown it is to be understood that any suitable number of these may be 25 used and may be connected, as usual, to move in unison to cause the ring rail I3 to move up and down under the control of the builder motion as is common and well understood in ring spinning machines. The winding lever 25 to which the builder motion chain, that is the section 23 thereof, is attached derives its motion from the rack 28 through action of a roll (not shown) fastened to the rack and coacting with the upper surface of the winding lever 25. Motion is imparted to the rack bygthe worm connection of a shaft 29. An intermittent motion is impart-ed to the shaft 2! by the ratchet 30 fixed thereon acting in conjunction with the pawl 3i carried on the arm 32 which is actuated by the rod 33 as the builder lever 26 is raised and lowered. These parts and their assembly are-disclosed in Letters Patent No. 1,491,808 dated April 29, 1934.

To suit particular requirements as to speed in the laying of the yarn onto the bobbin there is arranged an inverted substantially T-shaped bracket 34 upon the frame of the spinning machine and this bracket at the base arm 35 has provided therein an elongated slot 36 for accommodating fasteners 37 mounted in the rail l0 5| thus it being seen that the said bracket 34 is susceptible of adjustment longitudinally of this rail 10 to alter or change the position of the bracket.

In the vertical stem portion of the bracket 34 is a perpendicular slot 38 for vertical adjustable mounting therein of the attaching end 39 of a stud journal 4|] which is horizontally disposed. Loosely journaled on the stud 40 is a cam 4| having several stepped cam portions 42 and 43, respectively, and to the latter is hinged at 44 the chain length 22 while to the portion 42 is hinged at 45 the chain length 23 and under movement of these lengths in unison with each other a slow motion of the rail at the lower part of the spindles is secured and then gradually the motion is quickened at the upper part of said spindles whereby a larger number of yards of yarn may be wound on each spindle.

As indicated in Figures 1. and 2 of the drawing the cam 4| in its connection with the lengths 22 and 23 of the chain is such that when the chain is moved the said cam will be rotated for a part of a revolution. When the up and down travel of the rail I3 is begun said travel is usually at one and three-eighths inches but could be any desired number of inches and this travel is continually and gradually increased until the bobbin is full and the travel of the rail has increased to one and three-fourths inches. This increase of travel takes place after the bottom of the bobbin is filled with yarn to the desired diameter and the length of travel is caused by the initial setting of the bracket 34 which set ting is fixed by the fasteners 31. The original travel of the frame is one and three quarters inches and when setting the travel for one and three-eighths inches stroke such remains until the cam 4| revolves to a point where its flat surface 42 disengages chain length 23 which then rides onto the circular portion of said cam. This causes the stroke of the rail to increase to the natural stroke of one and three-fourths inches.

The provision of the cam 4| causes the speed of the rail |3 to increase as the cam 4| turns over due to the chain length 23 riding on to the surface 43 of the cam 4| at a greater dis tance from the center of rotation than the surface 42 (see Figure 3). It is to be noted that when the mechanism first starts the cam 4| is in the position as shown in Figures 1 and 2 and the chain length 23 is at the smallest diameter of the cam 4| and as the latter rotates this chain length 23 rides onto the larger diameter of said cam. The first part of the rotation of the cam 4| will cause the rail 3 to move gradually upwardly at substantially an even speed and when the chain length 23 engages the larger diameter of the cam 4| the speed will gradually increase in the movement of the rail I3 and in this manner of action the bobbins will be threaded tighter, eliminating all high end pieces and a great deal more yarn is placed on the bottoms of the bobbins and also a larger amount of yarn is Wound and this amount being arranged near the bases of the spindles.

In order to efiect the Winding of the yarn in the form of a bunch at the lower part of the bobbin the traverse of the ring rail is retarded by means of a locking latch 46 abutting against the builder lever 26. The latch is pivoted on a stud 41 fixed in a bracket 48 in stationary relation to the framing of the machine; the latch being provided with an abutment member 49 adjustably mounted on the lower part of the latch and a knock-01f roll (not shown) operating in conjunction with said lever to release the locking latch 46.

In operation the operative after starting the machine depresses the ring rail by means of foot pressure applied to the end of the lever l8 thus positioning the ring rail for the beginning of the bottom traverse of the yarn. This action also depresses the builder lever to its lowest position acted thereon by the cam (not shown) of the builder structure as disclosed in Patent No. 1,491,808. The operative then manually swings the latch 46 so that the part 49 rests on top of the lever 26 preventing it from moving upwardly thus rendering the ring rail stationary and causing the yarn to wind in a bunch; meanwhile, the rotating motion of the cam gradually brings the lug cam into contact with the knockoif roll, the shape of the lug cam being such that the locking action of the latch is removed from the builder lever and in consequence the builder lever resumes its upward and downward motion without restriction thus permitting the main winding of the yarn on the bobbin in the regular manner. The latch after being pushed from contact with the builder lever swings to such a position as to be just out of the path of the motion of the builder lever.

What is claimed is:

The combination with a flexible element for connection to a ring rail, a bunch builder, and a flexible builder element for actuation by the bunch builder, of rotatable means interposed between and attached to said elements for transmitting motion therebetween at variable speeds, said means including a rotating member to which the respective elements are connected, the member being formed with a peripheral recision to provide cam surfaces at different distances from the axis of said member and having the flexible elements attached to said surfaces respectively, and a bracket adjustably attached to a frame of a spinning machine and having a horizontally disposed elongated slot therein, means passing through the frame and slot for securing the bracket in selected horizontally adjusted position on the frame, said bracket also having an elongated slot disposed at substantially right angles to the first slot, a stud journal supporting said rotating member and adapted to be mounted adjustably in the second slot, and means for securing said journal in selected position in said second slot.
